Problems solved by technology
[0002] Methanol water in alcohol fuel cells needs to be vaporized before it can be reformed to produce hydrogen and enter the stack to generate electricity. The existing methanol water vaporization equipment adopts the form of flow channels combined with electric heating. The disadvantage of this vaporization equipment is that it is power Fixed, the size of the evaporation capacity is not easy to control, and the second is that the methanol water is likely to cause excessive flow resistance during the vaporization process, which affects the vaporization efficiency

The invention discloses an electrically-heating evaporator for alcohols. The technical scheme of the invention is as follows: the electrically-heating evaporator for the alcohols comprises two edge sealing plates, an evaporation module formed by a plurality of evaporation flow channel plates which are arranged between the two edge sealing plates in a superposition manner, as well as a liquid inletmodule and a gas confluence module which are arranged at the two sides of the evaporation module separately, wherein each evaporation flow channel plate comprises a snakelike flow channel; an inlet of each snakelike flow channel is connected with the liquid inlet module; an outlet of each snakelike flow channel is connected with an exhaust channel; the exhaust channel is connected with the gas confluence module; each snakelike flow channel is provided with a plurality of fluid pressure reduction ports which communicate with the exhaust channel, at a part close to the outlet, of the exhaust channel; and a plurality of electric heating rods and a temperature sensor are arranged in each evaporation flow channel plate. The electrically-heating evaporator for the alcohols in the scheme is adjustable in power and capable of reducing the flow resistance.
Description
technical field [0001] The invention relates to the technical field of fuel cells, in particular to an alcohol electric heating evaporator. Background technique [0002] The methanol water in the alcohol fuel cell needs to be vaporized before it can be reformed to produce hydrogen and enter the stack to generate electricity. The methanol water vaporization equipment in the prior art adopts the form of flow channel and electric heating. The disadvantage of this vaporization equipment is the power Fixed, the size of the evaporation capacity is not easy to control, and the second is that the methanol water is likely to cause excessive flow resistance during the vaporization process, which affects the vaporization efficiency. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the main purpose of the present invention is to provide an electric heating evaporator for alcohols with adjustable power and reduced flow resistance. [0004] In order to ac...
